- MEANS ron SUPPORTING TREAnLn MEcnANIsM.

To all whom t may concern Be it known that we, EMANUEL KAUF- MANN and ROBERT J. HoL'r, citizens kof the United States, and residing at Atlanta, in the county of Fulton and State of Georgia, have invented Certain new and `useful Improvementsfin Means for Supporting Treadle Mechanism, of which the kfollowing is a specification. c.

This invention relates to improvements in means for supporting treadle mechanism, being more particularly adapted for use in structures of the type shown in the application of Emanuel Kaufmann, filed AFeby. 3, 1913 Serial No. 745,937.

The structures referred to in said application pertain more particularly to tables for supporting a plurality of machines, such as sewing machines `and in which a plurality of` machines are driven froma suitable source of power supply, each machine being independently controlled as to operation. In the structure referred to, the machines are positioned in spaced apart rows with'the power supply located below the table and intermediate opposing table supports, a sectional bracket connecting opposing legs of the support, with the'machines located directly on top of the legs.

In devices of this character, the control is generally by means of the feet of the operator, and where the table structure is comparatively narrow, the power .supply generally in the form of a shaft, is brought very close to thev treadle structure, making it possible for the clothing of the operator to be` caught inthe shaft.

Another feature in connection with the structure of the application above identified is the ability to provide for a cleaning of the floor, beneath the table, the structure being provided in such form as to retain the entire structure out of contact with the floor and permit the formation of a suiiicient c,space below the treadle to permit a ready cleaning or sweepmg of the floor therebelow. lIn addition, provision is made for having the seat for the operatorcarried by the .supportingl leg and capable of adjustment vertically to suit the convenience of the operator.

The various conditions referred to are present in the ordinary type of table strucspeicamn f mamie-arent, Patented Aug, 53,1,19jt5jo Applicatonled February 3, 1913. Serial No. 745,941. j I l structionof the treadle support, this particularf'form of construction forming the subject matter of the present application.

The objects of the invention are therefore to overcome the objections indicated, `and at the ksame time to provide for adjustability and movability of the parts to meet these conditions; to provide a construction which can be readily secured in position and manipulated therein, which is simple and efficient in operation, durable in construction, formed of aminimum number of parts, and which can be manufactured atfa relatively low cost.

To these and other ends, the` nature of which will be readily understood as the invention is hereinafter disclosed, Vsaidy invention consists in the improved construction and combination of parts hereinafter fully described, illustrated in the accom-` panying drawings, and more particularly pointed out in the appended claims.

In the accompanying drawings, in' which similar vreference characters indicate similar parts in each of the views :Figure 1 is a viewrin elevation of apart of the table and machine supporting vstructure showingVY the present invention applied thereto, the latter being shown in end elevation. Fig. 2 isa detail View, partly in section, showing the supporting bracket, the guard, and the means for adjusting the angularity of the guard, the latter being shown in section. Fig. 3 is an elevation of the adjusting member. Fig. 4 is a horizontal sectional View taken through the supporting bracket and showing the guard and treadle `mechanism in plan View. VFig. 5 is a cross-sectional view taken through the guard and through one of the members for supporting the treadle. Fig. 6 is a cross-sectiontaken on th line 6 6 of Fig. 5. Y

In Fig. 1 of the drawings-we have shown a portion of the structure of a table supporting means, this structure comprising the leg 10, a bracket 11 having connection with the leg at two spaced apart points in order to firmly position the bracket, and Va section 12 connected thereto by means of a bolt 13, the section 12 being slotted to provide for adjustability in position of the section. The section 12 is adapted to support the power supply, and it is to be understood that `the opposing leg will havey a bracket and section similar to that indi-l cated at 11 and connected to the opposite end of .the section 12.. This general are rangement, together with theA idea'oflsupporting the treadle mechanism therefrom, is not specifically claimed inthepresent'ape plication, as it forms one of the features of the said applicationheretofore identilied.

The present invention deals ,more par-A ticularly with the specific construction of the treadle support, and in this construetion, 15 designates an arm having anopening t15 which receives thebolt 13, said arm having its lower end formed to provide a face 15b inclined tothe direction of length of the arm, said vface being adaptedto con tact with the face of. a guard plate 16, the guard plate projecting laterally of the arm and being of a length suiiicient for its pur-i pose; for instance, it may be a plate'which is intended 'simply for the vmachine unit and thus act solely, in *connectiony with a single operator, or it may be of a length to extend through aV plurality of units. ,It is preferred however, that the guard plate be individual for each unitin order that Yits adjustments maybe hadv to meet'individual conditions. Y .j e e v The arm 15 may `swing on the bolt 13, and in order to provide f oran adjustable positioning of the arm and thereby control the position of the treadle mechanism as well as the inclination' of the guard plate andthe distanceof the latter with respect to the power shaft, a suitable adjustable connector indicated at 17 is adapted to con-A each arm, the drawings showing screws 17e as employed for this purpose.

By means of the connector, the arm can be swung` on its pivot toany desired point, and fixedly held in position at that point through the adjustment of the connector, the arrangement providing for absolutely fixing the angularity of the arm 15 and retaining the guard plate in the adjusted position under the pressureoperations provided by the operator.

i As will be seen in Fig. 4, the arm 15 is located at one end of the guard plate 16, thus projecting the latter to place said plate in proper position below the feet of the operator. j y

The treadle isfsupported upon the guard plate by Ythel employment of two brackets `width ofv said guardplate, suitable adjustl8,.placed at spaced apart points on the upper face of'theiguard plate, said brackets being slotted as at 18a, by means of which they may be adjusted in the direction of 7o ing members 1S" being employed for the v purpose. Y

The brackets are each provided with projectingpairs of' ears 18C and between each pair of ears is pivotally mounted an arm 75 19 carrying the treadleQO, the latter having pintles 2Oa which are insertable within the arms 19, the pivot for said arms being indicated at 19a.

As seen in Fig. 5, the arms 19 andbrackets 18 are formed in such manner that a shoulder'19b ofthe arm is adapted to( contact with a shoulder on the bracket when the arms are in their lowered position, thisy arrangement providing a stop to limit the piv' otal movement of the arms in one direction. As shown in Fig. 6, each arm 19 is also provided with laterally-extending lugs 19C which are adapted to' extend against the under face of the ears 18C when the parts are in the position shown in full lines in Fig. 5, this vparticular arrangement providing a firm support for the arms and the treadle when the parts are in position for use, thereby placing the treadle mechanism ina convenient position for the feet of the operator and atthe same time providing a suiicient support against the pressure which is exerted on the treadle'by the operator in use.

As shown in Fig. 5, the arm 19 carrying 100 the treadle 2O may be swung vertically, thus carrying the treadle mechanism upwardly and placingthe parts in a more compact relation, enabling lthe sweeper to have better access for the purpose of cleaning the floor; 105 this position is shown in dotted lines in Fig. 1.

As will be readily understood, theentire treadle mechanism is supported from the post connections indicated by the sections 1110 11 and 12, thus retaining all of the parts entirely above the surface of the floor and in position tok permit a cleaning' of the entire surface thereof 'Furthermore any swing' ing movements of the arms19 for the pur- 1'15 pose of placing them in a more compact re-` lation can take place without affecting the adjustments lwhich were initially made for the purpose of providing the easiest position l for the operator. This fact inrconnection's 120 with the adjustability of the support as a whole through the connector and the pivotal mounting of the arm 15 makesl the device as an entirety, eflicient not only as a treadle support, but also as a guard plate which may be positioned so as to practically prevent any liability of the clothing of the operator being brought into contact with the power supply;

"While we have shown one form of coninvention as expressed in nector 17, it .will be understood that a similar result can be obtained by connectors in dierent forms, the invention not being restricted to the particular form' shown.

l/Vhile we have'r herein shown and described one form 1n which our invention may be applied, it will bev readily understood that changes and modifications therevin may be required or Vdesired to meet the exigencies of use, and wel therefore desire it to be understood that we reserve the right j to make any and all such changes and modications as may be required or desired to meet these conditions in so far as the samek `the direction of length of the arm,.a guard plate projecting laterally from the armand angularly disposed in correspondence 1 to the inclined face of the' arm, kand treadle mechanism supported on-said guard independently ofsaid` arm;
